Abstract
1,146,567. Diamines. DYNAMIT NOBEL A.G. 27 April, 1967 [28 April, 1966; 17 March, 1967], No. 19561/67. Heading C2C. Diamines of the formula in which R<SP>1</SP> and R<SP>11</SP> each represent H or an alkyl, cycloalkyl or aryl radical or together with the carbon atoms to which they are attached, represent a cycloaliphatic ring, are prepared by hydrogenating a nitrile of the general formula with hydrogen in the presence of at least a stoichiometric amount of ammonia in the presence of a hydrogenation catalyst. The reaction is suitably carried out at 50-200‹ C. in the presence of an organic solvent or liquid ammonia. The nitrites of general Formula (II) above may be prepared by hydrogenating those of general Formula (I) in the absence of ammonia at - 20‹ to + 70‹ C. in the presence of a noble metal hydrogenation catalyst.
